WORKI-IOLDING AND POSITIONING DEVICE FOR RULE AND BORDER TYPE OR SLUGP CUTTING MACHINES.

Application filed August 5, 1921. Serial No. 489,960.

To all whom it 71mg concern:

Be it known that I, JOHN Locum, a citizen of the United States, residing inPhiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in VVorkholding and Positioning Devices for Rule and Border Type or Slug-Cutting Machines, whereof the following is a specification, referencebeing had to the accompanying drawings;

My invention relates to work holding and positioning devices useful in connection with machines employed .in printers compos- 1 ing room's for cutting rule and border slugs.

Amongst the objects of my invention are to make it ossible to miter and, at the same time, to cut a multiplicity of rules or borders to uniform lengths in a single operation; to

miter simultaneously, a series of rules and borders arranged in ordered sequence and intended for use in making up composite borders; and in general, to facilitate miter ingof rules and borders so that this op- 2 eration may be accomplished, not only with greater ease, but more acciirately and ex peditiously than heretofore with a view towards effecting the utmost possible saving 'ofti'me and labor.

Other objects and attendant advantages of my invention will become readily apparent from the detailed description which folv lows: I v I In the drawings, Fig. I is a plan viewof a rule and border slug machine conveniently illustrating the use of my invention-.-

Figs. II and III are similar views showing the necessary steps. in setting the machine to miter rules and borders of very short lengths.

Fig. IV is an illustration similar to the above showing my invention as it is used in mitering rule type.

Fig. V is a perspective detail, view showing my improved work holding and p0sition'ing device on an enlarged scale.

F igs..VI and VII are views showing two difierent types of abutment blocks which may beinterchangeablyused in cutting mitersof difl'erent angles; and

F igf VIII isa detail cross sectional view alongthe'lines VIII-VIII in Fig. I.

In ord'er to facilitate the ready understeiidihg ofniyinvention, I will fiist d- I various angular scribe, briefly, a cutting apparatus or machine wherewith it is adapted to be used.

, plained more definitely later, the rule or border slugs to be cut may be moved relative to the cutting tool which, in the present instance, is in the form of a rotary saw disk 3 secured upon a shaft 4 journalled in appropriate bearings 5-5. The saw is actuated bya pulley 6 adapted to be driven by a belt, with a suitable motor (not shown) preferably located beneath the table 1. Shifting of the work supporting section 2 of the table is efieoted under control of a hand crank 7 wherewith is associated a graduated dial 8 and a coordinative fixed pointer 9.

Mountedto thetop of the movable section 2 of the table is a. gaugedevice comprehensively designated in the drawings by the numeral 10 and by aid of which the slugs to be cut may be set or placed in various angularjpositions with respect to the cutting tool or disk 3. Said gauge device comprises a swivel member 11 to the under side of which, and through the instrumentality of a screw pin is secured a slide sector 13 wh1ch,,pro ects into and is guided by an \arcuatslotl ifin the table section 2, said slot having its generating center in the plane of the front face of the cutting disk 3. The gauge member 11 may be set in I positions with respect to the cutting tool 15 which is registerablewith apertures 16 lnthe movable section 2 of the table. Associatedwith the gauge member 11 is an auxil ary gauge member 17 which is slidable relatively under guidance of a longitudinal undercut slot 18 in the former; The auxs iliary.gauge member 17 hasan extension in the form of a finger 19 whose straight edge 20 15 perpendicular to a similar straight edge 21 along the side of the member 11. The auxiliary gaugemember 17 has, furthermore, integral; lugs 2222 between which" scr w a is otatively sup by -means' of a locking pinported. Said screw worm engages with a machined rack 24 of the member 11, and thus constitutes a micrometer adjustment means. The pitch of the screw threading 1s based on the point as a unit, and in practice the screw'worm is graduated circumferentially so that adjustments may be had which are fractional to the graduations along the top of the gauge member 11 ad jacent its straight edge 21.

A work clamping means or vice also forms part of the standard equipment of a cutting machine such as herein illustrated. This vice, it will be observed, is secured upon th top of a movable table section 2 along that side which extends adjacent to the front face or" the disk 3, and comprises a rod 26 adapted to be set in different extended positions by a suitable locking means operable through a handle bar 27. By this means. the slugs indicated at T may or dinarily be engaged at their forward ends and securely clamped against the straight edges of the gauge member 11 so that the possibility of accidental displacement during the cutting operations is positively pre vented. The work holding and positioning device of my invention comprises two sets of blocks of two different species such as indicated by the numerals 30 and 31 in Figs. VI and VII and which in practice correspond in number to the various angles likely to be used in mitering and which are so identified as suggested in the illustrations. These species are readily distinguishable by reason of the difference in the character of their beveled ends while the individual elements oii each set differ only in the slope of the bevel. The blocks of one set have notches 32 in their sloping ends and the others are simply plain as indicated at 38. The rea sons for such distinctions will become readily obvious from subsequent explanation and the description for the present will be confined only to those features which are common to all of the blocks. Referring for a moment to Fig. V of the drawings, it will be seen that the block 30 has its upper surface recessed as at 35 for accommodation of the end of the laterally extending plate 36, which, in order to allow of interchangeability of th blocks, is removably secured by means of a thumb screw 37. Attached to the under side of the plate is a slide piece 38 having a configuration corresponding to that of the longitudinal undercut slot 18 of the gauge number 11 and is elampable within said slot by means of a knurled thumb screw 39 to hold the block in different adjusted positions.

For use in association with the block to assist in holding the type, or slugs to the straight edge 21 of the gauge member 11, I have provided retainer strips such as shown at 40. The strip is adapted to overlap the inner ends of the slugs and in order to allow adjustabilitv relative to a block, is slotted longitudinally as at 41 for passage of a clamp screw 42. The retainer strip has a head 43 which is notched as indicated at 44, for cooperation with the end of the extensible bar 26 of the vice 25. An upstanding lug 45 of the head 43 serves as a means whereby the strip may be grasped in adjusting, and the latter in the course of such adjusting is guided by the overhanging end of the plate 36, see Fig. V.

In Fig. I. I have shown the manner in which a series of slugs may be mitered to an angle of degrees in accordance with my invention. The block of the type 30 identified with the number corresponding to this 1 angle is employed for this purpose and from the illustration it will be apparent that the function of the steps or notches32 in the beveled end of the block is to accommodate the abutting ends of the slugs. Thus when the gauge device 10, as a whole, has been swung to an angle of 60 degrees, the beveled end of the block will lie parallel to the trimming disk with the result that the slugs will be cut to uniform lengths. If within the scope of the graduations of the gauge member 11, adjustment of the block may be made without aid of the auxiliary gauge member 17. If, however. finer adjustment should be required, the screw worm 28 may be employed in a manner already understood. After the slugs have been properly positioned as explained. the retainer strip 40 is adjusted so that the notch 44 of the head 43 is in line with the extensible bar 26 of the vice 25 whereupon said bar is drawn forward and locked by proper manipulation of the handle bar 27. From the above it will be seen that by my invention, a number of rule or border slugs may be cut to uni-' form lengths and at the same time mitered to any desired angle.

When exceedingly short slugs are to be mitered I proceed in the manner suggested in Figs. II and III. From the former of these illustrations it will he ol'iscrvcd that the block 30 (when it is necessary to employ the auxiliary gauge member 17} is set while the gauge mechanism 10 occupies a normal position. and. before the latter is swung. the auxiliary gauge member l? is withdrawn in the extent ne essary to avoid engagement with the cutter disk '3 when the table section 2 is moved in making the out. lieretotore in cutting short slug lengths. it has been ne essary to employ a number of tillers iu eu mediate the straight edge of the gauge element and the slugs. to avoid engagement of the finger of auxiliary gauge member 17 with the cutter disk 3) and these fillers of necessity, had first to he cut accurate y LO lengths whiGh resulted in considerable loss of time.

a block of the species'31 in the manner sug"- gested in FigpIV, In this way itis possible to make up in the case of border slugs, a composite border which, as will be appreciated by those skilled'in the art to which my invention pertains,could not be done heretofore without trimming the bars individually.
